It is designed as standard equipment compatible with all common spacecraft interfaces and mission constraints. The level 2 SREM data sets contain count rates (1/s) as measured by the Standard Radiation Environment Monitor (SREM) instrument on the Rosetta spacecraft, along with their standard deviations. The archive content and structure is summarised below. ============================================================================== SREM Data Archive: ============================================================================== a) S/C Data ========================= CODMAC Level / Type Data Type Data Content 2 / EDITED Data ASCII table Count rate Data The data can be found in the following directory: */DATA/ b) Supporting Files ========================= Supporting files for the Archive end user include PDS documentation, descriptions and searchable indices. These are organised into three sub- directories immediately below the root directory: - CATALOG - DOCUMENT - INDEX ============================================================================== Structure of the Volume: ============================================================================== Root Directory | |--- AAREADME.TXT (PDS required introduction to the data set ) | | |../CATALOG/ | | | |--- CATINFO.TXT (List of the CATALOG folder contents) | |--- DATASET.CAT (Description of the data set) | |--- INST_SREM.CAT (Description of the SREM instrument) | |--- INSTHOST.CAT (Description of the Rosetta spacecraft) | |--- MISSION.CAT (Description of the Rosetta mission) | |--- PERS_SREM.CAT (List of relevant personnel for SREM) | |--- REF.CAT (List of references for the Rosetta data sets) | |--- SOFTWARE.CAT (Information regarding any software for SREM) | | |../DATA/ | | | |--- *.TAB Files (Data products in ASCII table format) | |--- *.LBL Files (Detached label files for each data product) | | |../DOCUMENT/ | | | |--- DOCINFO.TXT (List of the DOCUMENT folder | | contents) | |--- EAICD_SREM.PDF Files (PDF version of EAICD) | |--- EAICD_SREM.LBL Files (EAICD label) | |--- SREMDC_FINAL_REPORT_V1.0.PDF (PDF version of Final SREM | | Data Consolidation Report) | |--- SREMDC_FINAL_REPORT_V1.0.LBL (Detached label for the SREM | | Data Consolidation Report) | | |../EXTRAS | | | |---*.cdf Files (CDF format files of the DATA products) | | | | |../INDEX | | | |--- INDXINFO.TXT (List of the INDEX folder contents) | |--- INDEX.LBL (Detached label file for INDEX.TAB) | |--- INDEX.TAB (Index of the data set in tabular format) | | |---VOLDESC.CAT (Volume description file for the SREM data) The ROSETTA project decided that the data would be archived in the PDS Version 3 format and, consequently, the layout of this volume and all associated label files for each file conform to the PDS / PSA guidelines. ============================================================================== Contact Information: ============================================================================== Data generated by: Francisco Vallejo ESA/ESAC Villanueva de la Canada, Madrid, 28692, Spain. fvallejo@sciops.esa.int ==============================================================================
